i need help for SKA!

hi friends!
for years, ive been looking for ska riffs and samples, never found anything relevant. its even more incredible when you see the importance of dubstep today…this is the origin of it all!
my unreachable goal would be to find sounds in order to make a fun song like (old memories!) orbital’s ska’d for life : this is so cooool

never found enough chords to have a riff, never found such a bright synth, neither so nice brass…i suppose they all sampled by themselves…

maany sounds in this track amaze me, even more when i realize this song is about ten years old…

please renoise people, help me find sauces to make soemthing like this!
